Four ECM ubiquitous protein components, each of which comprises multiple, distinct, repeating domains, are found in basal laminae. Given below are a list of some extracellular matrix (ECM) proteins in column A and their characteristics in column B.

Column A	Column B
a. Type IV collagen	i. a large multidomain proteoglycan that binds to and cross-links many ECM components and cell-surface molecules.
b. Laminins	ii. a rodlike molecule that cross-links type IV collagen, perlecan, and laminin, which helps incorporate other components into the ECM and also stabilizes basal laminae.
c. Perlecan	iii. a family of multi-adhesive, cross-shaped proteins that form a fibrous two-dimensional network with type IV collagen and that also bind to integrins and other adhesion receptors.
d. Nidogen	iv. trimeric molecules with both rodlike and globular domains that form a two-dimensional network.

The amount of change in q is directly proportional to the migration (m); The magnitude of change is also affected by the differences in allelic frequencies of the two populations (qI - qII); What is amount of change when 200 migratory individuals are merge in recipient population size of 1800. Allele frequency of q1 of source and recipient population is .80 and .20 respectively.

Imagine a plant of extremely variable height that is pollinated by three different pollinators, one that was attracted to short plants, another that preferred plants of medium height and a third that visited only the tallest plants. If the pollinator that preferred plants of medium height disappeared from an area. What is concluding of this condition?
